Created attachment 123356 [details] dmc_FW I guess this bug belongs to the DRI component, but feel free to assign the bug to the component owner if I'm wrong. After installing DMC driver 1.06, it shows as not loaded in APL platforms. These are the results: # /lib/firmware/i915# ls -l total 12 -rw-r--r-- 1 root root 8380 Apr 29 06:37 bxt_dmc_ver1_06.bin lrwxrwxrwx 1 root root 38 Apr 29 06:37 bxt_dmc_ver1.bin -> /lib/firmware/i915/bxt_dmc_ver1_06.bin # cat /sys/kernel/debug/dri/0/i915_dmc_info fw loaded: no path: i915/bxt_dmc_ver1.bin program base: 0x7f7b1076 ssp base: 0x00000000 htp: 0x00000000 -------------------------------------------------- This is my current configuration: Software information ================================ Kernel version : 4.6.0-rc4-drm-intel-nightly-ww17-commit-1e81bac+ Linux distribution : Ubuntu 15.10 Architecture : 64-bit Bios revision : 129.10 KSC revision : 1.6 Hardware information ================================ Platform : BXT-P Motherboard model : Broxton P Motherboard type : NOTEBOOK Hand Held Motherboard manufacturer : Intel Corp.
